The Mitutoyo Inch Rectangular Gage Block sets offer exceptional precision and stability for calibration and manufacturing traceability of standard-sized pieces. Mitutoyo gauge blocks are recognized to be of the highest quality in Japan and internationally and are available in various grades to meet every need in respect of working conditions, environment, and application. Gage blocks are available in different grades and sizes, offering exceptional precision and stability for calibration and manufacturing traceability. The Mitutoyo innovative lapping technique makes their gage blocks some of the most accurate and trusted instruments in the world, featuring exceptional flatness and ideal surface roughness. Mitutoyo steel gage blocks are constructed of high-carbon, high-chrome steel.

Accuracy - Mitutoyo has established a traceability system for measurement products, up to the Metrology Management Center of the National Institute of Advanced Industrial Science and Technology (AIST), and has been certified by the Japanese government as an accredited laboratory.

Wringing - The Mitutoyo advanced lapping technique, developed for more than a half-century by Mitutoyo, achieves the best flatness and surface roughness needed for gage blocks.

Steel Blocks - The Mitutoyo steel gage blocks are constructed of high-carbon, high-chrome steel. High-carbon, high-chrome steel is employed to sufficiently satisfy a variety of material characteristics required for gage blocks. A high degree of hardness, obtained by Mitutoyo heat treatment technology, as well as methodically repeated heat treatment, has successfully reduced deterioration change over time.
